Concert Band Club. Set. Music Stand. Trumpet. Mouthpiece. Tuner. Metronome

This is a used item that was used by a child. I am selling it because I have purchased a complete set and no longer need it.
It was used for about three months.
⚪︎YAMAHA TR16C4 Mouthpiece for Trumpet
⚪︎Valve oil (half remaining), grease, and 2 other types
⚪︎SEIKO STH200BK Tuner Metronome
⚪︎ZEN-ON Music Stand (with scratches from use)

All of these are used items that were actually used. Also, I am not knowledgeable about musical instruments, so please refrain from purchasing if you are looking for perfect functionality.

If you have any questions, please feel free to ask in the question section. I will answer to the best of my ability. Please adhere to the 3N rule (No returns, No claims, No cancellations).
